skilled in t-hisart without a more detailed The present embodime t of the invention has been A disclosed in considerable detail merely for the purposes of exemplificatio-n since in actual practice it attains the teas tures of advantage enumeratedas desirable in the statement of the invention and the above description:

It will be apparent that changes the details of construction, and in the combination and arrangement of parts may be resorted to the inner pivoted end of the arm being rounded, an elongated coil spring having one end engaged with the periphery of said rounded end, a'cylin der, a piston in the cylinder, a rod connected with thepiston and extending through one end-.ofthecylinder and connected with a the spring, and means for creating a vacuum in thejother'end of the cylinder formoving the piston and thereby actuating the signalling arm, a bolt, between ithout departing from the spirit. or scope .;of the inventlon as hereinafter cla med or sacrificing any of its advantages.
